Have you uploaded correctly? I guess you need to upload the Ajax Toolkit dlls also. Have you done that?

yes i had uploaded it . its in bin directory.. :(
Okay try this. Clean the Project, then Build again. And after that upload all files and bin again. Then Reset the IIS. See if it solves the problem or not.

This Works for me Thanks
You may solve this issue by setting the Copy Local attribute of your project's references to true!

Instructions

1- In Solution Explorer, click the Show All Files button to display the References node.
2- Open the References node for the project.
3- Right-click a reference in the References list, and click Properties.
The properties associated with that reference appear in a list in the Properties window.
4- Select Copy Local from the left-hand column, and then click the arrow in the right-hand column to change the value to True or False.

You may also use the following code to identify what is missing

C#
<pre lang="c#">
using System.IO;
using System.Reflection;
using System.Text;

try
{
//The code that causes the error goes here.
}
catch (ReflectionTypeLoadException ex)
{
StringBuilder sb = new StringBuilder();
foreach (Exception exSub in ex.LoaderExceptions)
{
sb.AppendLine(exSub.Message);
FileNotFoundException exFileNotFound = exSub as FileNotFoundException;
if (exFileNotFound != null)
{
if(!string.IsNullOrEmpty(exFileNotFound.FusionLog))
{
sb.AppendLine("Fusion Log:");
sb.AppendLine(exFileNotFound.FusionLog);
}
}
sb.AppendLine();
}
string errorMessage = sb.ToString();
//Display or log the error based on your application.
}

Change the asp:ToolkitScriptManager to

XML
<asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server">
</asp:ScriptManager>

it worked for me!
If it works on your local machine, the issue is that you have not copied the dlls to the server.
